Topping and Harvesting Trials Topping to 24 leaves

Topping and Harvesting Trials Topping to 24 leaves tends to increase yield but not always significantly. Harvesting at 6 weeks instead of 4 weeks tends not to increase yield, but may significantly decrease quality.

Sucker Control Trials Treatments were applied using either fine or coarse nozzles. Coarse nozzles have been shown to producer better control than fine spray tips. The experimental product A 1601 did not perform as well as Butralin in both trials or Prime+ in Adair Co. Reducing the MH rate to 1. 5 gal/a and adding Butralin or Prime + has proven to increase control and reduce residue. That difference was not as clear in 2004 as it has been in previous years with different weather.
